About Manifest

Manifest is an open-source LLM gateway for AI agents and apps. It connects API keys, subscriptions, and local models to one OpenAI-compatible endpoint and routes each query to the selected model, including an "model": "auto" option.

It includes custom routing, fallback when queries fail, full body logs for success and error messages, and cost tracking with notifications and limits. It is available as a cloud version and as a Docker image for self-hosting; the npm-based self-hosting path is no longer supported.

Key features

  • Single OpenAI-compatible endpoint for API keys, subscriptions, local models
  • Automatic model selection with "model": "auto" routing
  • Fallback to different models when queries fail
  • Full body logs for success and error messages
  • Cost tracking with notifications and limits
  • Self-hosting via Docker image and deployment templates
Best for: Developers running AI agents or apps that need multiple model providers through one endpoint.
Good for
  • Open-source with Docker self-hosting and a cloud version
  • Connects to 300+ models through 35 built-in connections plus custom endpoints
  • Supports API keys, subscriptions, and local models without single-provider lock-in
Watch out for
  • Old npm-based self-hosting path is no longer supported
  • Volume-backed templates are single-instance; horizontal scaling needs S3-compatible storage
  • Provider model lists are representative and discovered dynamically after connecting credentials

Manifest FAQ

How is Manifest self-hosted?
Manifest ships as a Docker image. After running the install script, open http://localhost:2099 and sign up; the first account becomes the admin.
How does model routing work?
Requests go through one OpenAI-compatible endpoint. Sending "model": "auto" lets Manifest pick the model.
Is the old npm self-hosting method still available?
No. The npm-based self-hosting path is no longer supported; use the Docker image or a deployment guide.
Is something wrong or out of date?
